Hello Everyone,
First, I'd like to share a friend of mine's very interesting project: Its an old RX7 chassis with a Ford 302. If that wasn't enough it has a big rear end with quick change gears. If that really wasn't enough, we designed and implemented an SLA front suspension, ditching those ugly stock struts.
Here are a few pics of the front and rear suspensions:
Anyway, with the front suspension finished, we're now working on the rear end. The current question is on front & rear track widths.
The front suspension is done and the track width is 59" from hub face to hub face. We plan to use 0 offset 10" wide NASCAR wheels. (we used NASCAR spindle and A arms, too)
The rear track width is currently 61" wide. We plan to run the same 10" 0off wheels in the rear.
Now the question we face is do we want to reduce the rear track width?
Here are some more facts. The stock RX7 had a wheelbase of 65" (we plan to keep this, but offset it an inch forward for weight distro reasons), a front track width of 56" and a rear of 55".
We noticed that a lot of sports and race cars have a wider front track than rear. If we were to shorten the rear axle we would have to slightly tub the rear of the car for clearance, get new axles, and shorten the tubes.
What do we need to consider in determining a proper rear end track width? Any advice would be much appreciated.
